Art Deco Travel Poster of a Seaplane Harbor at Dawn — ChatGPT Prompt

The Prompt

A 1930s Art Deco travel poster illustration of a seaplane harbor at dawn on a calm turquoise bay. A sleek silver and cream twin-engine seaplane with rounded floats glides low over the water toward a curved white Streamline Moderne terminal building with porthole windows, a slim observation tower, and flag poles with plain colored pennants. Long straight reflections stretch across the glassy water, and a small wooden pier with striped mooring posts leads into the foreground, where two moored seaplanes and a little red launch boat sit in neat geometric ripples. Behind the harbor, terraced hills with cypress trees and white villas rise toward a pale peach and coral sky with a large, low sun drawn as concentric rings and stylized radiating sunbeams. Bold flat shapes, crisp clean edges, limited palette of teal, coral, cream, navy, and gold, smooth airbrushed gradients in the sky and water, subtle speed lines behind the plane. Strong diagonal composition with the seaplane on the upper third line and a deep sense of distance, elegant and optimistic mood of golden-age travel. Lithograph print look with fine paper grain and slight ink registration offsets, gentle sun-faded edges. Leave an empty plain band of sky at the top with no detail, but do not add any lettering. No text, no letters, no logos, no airline markings, no people in close-up. Vertical 3:4 poster aspect ratio.
